IMPROVEMENT IN VIBRATING JOINTS FOR DEIEP WATER-PIPE LAVlNG.

Specication forming part of Letters Patent No. l 81,917, dated September5, 1876 application file August 18, 1876.

To all whom it may concern: v

Be it known that I, JAMES GURRAN, of Baltimore city, in the county ofBaltimore, and State ot' Maryland, have invented certain new and usefulImprovements in Laying Pipe in Deep Water-viz., a vibratin g joint tofacilitate the line iinding the prole ot' the bed of the stream; and do.hereby declare that the following is a full, clear, and exactdescription thereof, reference being had Ato the accompanying drawings,and to theletters of reference marked thereon, making part of thisspecification.

The nature of my invention consists in the construction and arrangementof a pipe-counection or vibrating joint, which will facilitate 'the lineconforming to the bed on which it is laid, as will be hereinafter morefully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I Will now proceed to describe itsconstruction and operation, referring to the annexed drawing', whichrepresents a plan view, part in section, of my pipeconnection. l

A represents an ordinary T-joint, to the center arm ot' which onesection of the watermain is to be connected in the usual manner. To theside arms of the T-joint A are attached ysuitable elbows B B,terminating with short tubes C C, directly opposite and parallel withthe side arms of the T-joint. The outer ends of the short tubes C C areformed with circumferential danges a, and t against shoulders b made inthe side arms D( of a Vibrating T-joint, D. The end of each side armD/is formed with an exterior flange, d, and a anged stuffing-box, Gr, isinserted in the end of each arm, D', surrounding the tube C, and saidstuffing-box is connectedto the flange d by nuts h, having nutsz'screwed upon their ends. 'lo the center arm of the T-joint D the nextsection ot' the Water-main is to be connected in the usual manner.

` It will readily be seen that by reason of the vibrating joint D thewater-main will adjust or accommodate. itself to the profile ot' the bedon which it is laid without any strain whatever on the pipes or joints.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

'lhe vibrating joint D, with side arms D and stuffing-boxes Gr, incombination with the tubes C, elbows B, and T-joint A, substantially asand for the purposes herein set forth.

In testimony that I claim the foregoingv I have hereunto set my handthis 10th day of August, 187 6.
